'Application filed April 19, 1912. Serial No. 691,929.

.-leit known that I, WILLIAM G. Barz, a cltlzen` of theiUnited States, and a resident vof the city of Chicago Heights, county of Cook, and` State of Illinois,'have invented certain new andv useful Improvements in Pumps forgCleaners, oflwhich the following is a specfication.-

This invention relates to new and usefull improvements in pumps for vacuum cleaners, andis designed to provlde amanually operabledevice Whichwill createv a constant suction through the hose and eliminate the lintermittent suctionsl 4which have been .prevdominant, in; the art heretofore.

Itl is also an object of .the present inventionk tok rovid a device of this character which willi be ,provided with mechanisms forl lfiltering por'4 operating upon the air Aa lsecond time in order to: Insure the entire removal of all line particles of 4dust or foreign mat-` ter therefrom prior to exhausting the same.

With the` above and other objects in v ew, this' invention consists in the construction', combinatiom and arrangement' of parts, Lall as hereinafter more fully described, claimed, the annexed drawings', wherein :-4 y l Figure 1 is atop plan view of the vacuum forming4 thel subject. matter of Ithe present invention, Fig. 2 is a central vertlcal.longitudinalsection thereof, Fig. 3 1s. a

similar view illustrating a changed positionofthe parts, and Fig. i is a front end elevation,parts thereof being. taken away to illustrate the interior thereof.

The vacuum cleaner forming the subject matter of ther present invention comprises a base provided with a supportin plate or platformhinged thereto throng dium of re-lbentpleaf springs interposed between the. base 'and'jsaid platform or plate. The u ,4 er'sideof said latform carries suction anii exhaust `cham erswhich coperate with bellows .or pneumatics for the purpose of creating the necessary suction and eX` haust ofthe present invention. I

Reference being had more particularly to lindicates a base provlded with 4suitable casters 11 at one terminal thereof and rubber-knobs 12 at the opposite ter# f said knobs being elevated above the corduring the transportatipncf the device. A platform or plate 13 is hmged described,

the. me-

A,meshesof thebag 25.

ved to' assume-the position illustrate f3.- The plate 30` constitutes a flap. valve and to lthe forward terminal of the base 10 means of the. rebent leaf springs 14 lwhich retain said platform or plate at an angle to l the base 10, as clearly illustrated in Figs. v 2 and 3. The under side of this platform 13 iS provided with a pneumatic or bellows 15, the movable section 16 of which is connected to the rear'end of the base l0 by the links 17 which are interposed between said movable section and said base. The stationary side of the -bellovvs or pneumatic 15 is embodied lin the rear terminal of Athe platform or plate 13.

A cover 18 1s rigidly secured to the Yrear terminal of the platform or plate 13 and has 1ts forward terminalspaced from the lower or hinged terminal of the platform or lplate 13 by the' vertical standards 19 which are located upon eachv side ofthe door, as will hereinafter be more fully. described. This cover 18 inl combination with the, platform orplateA 13 and the front, to be hereinafter constitute va chamber which is divided into the compartments 2O and 21 by the'partition 22.' The suction compartment 20 is closed by a door or front 23 interposedbetween the standards 19, said door or front being removable for the purpose of permitto be hadY to the compartment 20.

ting access A rame 24 is located in the compartment 20 adjacent to the inner surface of the d'oor 23,

and carries a bagj 25 which receives the dirt and dust brought througlh the union 26 which centrally pierces, t e door or front 23 and is connected 'to the suction hose 27. The compartment 20 is connected by the opening 28 with the bellows 15, said opening being desiglned to permit the passage of the air from t je' compartment 2O into.'said bellows after the 'same'has' passed through the The compartment 21 is connected to thebellows or pneumatic .15

by a plurality of openngs729 which l'lare' covered by a spring plate 30 secured upon the latform or plate 13 upon the interior of ,It e compartment 21 and. constructed of sprin material, said' plate, when not subject -to any outside pressure, bein' -adaptin Fig.

is designed 'to close the openings- 2.4, as illus trated 1n`Fig.2..' Y i Carried by thecover 18 adjacent; tothe rear terminal thereof, is a secondary bel'- sov lows 31, thegs'tatinnary side ktlfierieo being" lmatic '31 'by means of the openings'or ports -36. These openings 3G yare covered by a springmetal plate 37 which is similar in construction to the plate 30 and is adapted to normally assume theposition illustrated in Fig. 2. The exhaust chamber 34 is connected to theexterior atmosphere by means of the opening 38 formed in theforward terininal of said exhaust chamber which connects with a compartment 39, said compartment being provided with a hinged lid 40,`

pierced adjacent to theiorward edge thereof by the openings 41. Disposed directly.

under these openingsand to one side or. the port 38 is a dust tray 452, While superposed 'above said dust tray and extending entirely across the compartment is a screen 43. llty 4will clearlytbe seen thatthe air passing through the exhaust chamber 34 through the.

' opening 38inust passover the dust tray 4:2

pertinent 2l.

prior to being exhausted through the openings 4L Y,

. ln orderto provide a means for actuating the present invention, a yoke 44 spans the entire'deviceand is pivotally'hinged to the side Walls thereof interposed between the ltop 18,

' the plate or plati'orin l?) and the standards 19. This yoke carries a rearwardly extending arm 45 which is provided with a bifurcated terminal 46. This bifurcated terminal @engages theroller t7 operating. upon a bearing or bracket 48 mounted upon the. rear vterminal of the movable section 32 of the device. From the foregoing derstood that the operation of the present invention is as ollowsz'Assuming the elements of the device in the position illustrated in Fig. f2, the pressure is applied to the handle 49 of the yoke-14 .thereby moving the arm or lever vt5 in an` upward direction, thus causing 'the movable section 32 ot the bellows or pneumaticl to be raised, Which-naturally creates a suction in the coin- This' movement of the yoke to be exerted upon the plate i yca uses pressure or platform 13, thereby moving the same downwardly and compressing' the bellows or posite yside of the plate ifwhich causes said plate to be raised, permitting the air to pass it- Will clearly be uning saidv compression compartment' Wim :in-sense elements to again assume the 'position illus'- tratedl in Fig. 2, creating a suction in the compartment 20, and af pressure .in :th-ebellows 3l. 'lhis'causes a traiisteiotlie air trom' the.' compartment 21 and; f ebellows 3l through the ports 3G, the` pressure of said air releasing the plate or valve 3T and per mitting' the air to pass into the exhaust chamber 34. The air then leaves the exhaust chamber 34, owing to the continual pressure exerted thereon by the operation of the pres-v ent invention and passes vrinto the compartment 39 over the tray 42 through the screen 43 to the kexterior atmospherajleaving ali tine particles dust not1 re'taincd'iinthefj bag in said tray. This nat'urally-creates a constant suctionA inthe hose 2*( through the bag' Q5 depositing he dirt therein-'and thence through the balance of the elei'nents, as has been heretofore described.
